4 Problem resolving
Error description Possible course
The connected sensor does not generate any
signal
Is the sensor supply present?
1. Is the CF-MASTER in the general system menu
selected to ‘YES”
2. If 2 or more PICAS units are used and the CF
are synchronized, only 1 PICAS must have the
CF-MASTER to ‘YES’, At the other units the CF-
MASTER must be at ‘NO’.
Check the cabling of the RS485 connectors.
The measurement signal is changing with a slow
sinus wave form.
When more PICAS units are used together, it is
possible that the different carrier frequencies will
influence each other. In this case the PICAS units
must be synchronized (see General system menu)
The linearity of the signal is not within
specifications.
When the sensors have a higher impedance, a
error may occur at the input. To compensate this,
the correct impedance must be entered in the
general channel menu.
